as most of you know, My little coach is only 26 foot long, and thats bumper to bumper...

I am trying to figure out how many roof airs I need.

Any suggestions?

Proud single custodial dad to a wonderful 14 year old son, Owner of a 1986 Neoplan 26' transit Bus AN408, Great weekender...Lots of work to come on this bus, can't wait to get her done! 8.2L with a Allison AT545...

I went with 3 roof units...15K each. Basement was quite a bit more money and I didn't want to raise the roof. If you go basement, you should plan on a roof raise to accomodate duct work. This being my first, I wanted to keep it simple....and it still took 3 years to build.

Cat and I saw a 45' Dutch Star last fall that had 6 roof airs on it.Let's see, 45 divided by 6 = 7.5' per A/C So using that we can surmise that 26 divided by 7.5 =3.4666666666666666666666666666667 A/C's.So now we can round it up, since obviously the Dutch Star, being more expensive has better insulation We'll call it 4 roof airs. That should allow you to keep the temperature about 34° in Death Valley in July. It'll also help keep the beer a lot cooler so you don't have to work the fridge so hard.Of course, you'l probably need 2 12.5 KW diesel gensets, but Hey, who's counting!

As everything else, it would depend on what your plans are for the bus. I do not like hot weather - so, I want to travel in temps that are more reasonable. Considering this might help you make the call...

I have heard it said, "life comes at you fast". I didn't know it would be in the shape of a bus :-)

I had a class A, 34 foot. Two roof airs. Insulation was pretty good. White roof.

We about had heat stroke in Blyth CA, when the temps passed 120 degrees. Had both roof airs and the in-dash A/C going as well.

Ever since then, I've been a big fan of more rather than less A/C units. On our 40' bus, we have 3. And I've never regretted having more a/c units. If you aren't using it, then turn it off. If you need it, it's there.
